Just to clarify: correctly using version information is pretty
complicated, but using version information to work around bugs _looks_
like a simple solution. This means it gets used frequently, and most of
the people doing so do it wrong. Not because they couldn't do it right
if they tried, but because they don't even realize they need to try.
